GSS Compact Sampler
Section 1 Introduction
Welcome to the GSS manual and thank you for your purchase of
the Teledyne Isco GSS automated wastewater sampler. To learn
more about the general use of the GSS and its features, please
refer to the appropriate sections within this manual.
1.1 Product Description
The GSS is a compact portable sampler that is designed to meet
the needs of NPDES permit compliance and stormwater run-off.
Its small size and weight make it easy to handle and transport
from site to site. At the heart of the sampler is the GSS controller. It is environmentally sealed (rated NEMA 4X, 6, and
IP67) to provide protection from accidental submersion and long
term exposure to high humidity and corrosive gases. Its tactile
keypad and 2 line, 20 character display simplify operation.
The GSS sampler collects a liquid sample and places it in a one
gallon sample container. A dependable peristaltic pump delivers
the liquid to the bottle.
Any time the sampler is on, rainfall pulses will be counted. For
purposes of triggering a sample, the sampler will continuously
maintain the amount of rainfall occurring in the current 24-hour
period. Each minute, the amount of rainfall accumulated in the
oldest recorded minute will be deleted and the amount of rainfall
accumulated in the most recent minute will be added.
Historical data for the current and 14 previous days (midnight to
midnight) will also be stored and can be retrieved through the
keypad. If the sampler is inactive (shut off or not powered) for
some part of a 24-hour period, it will record the elapsed time it
was inactive. When displaying the rainfall for a time period, the
sampler will note if the sampler was not active for part of the
period and the display will indicate the percentage of the time
that the sampler was active (turned on). For days that the
sampler was inactive for an entire day (midnight to midnight),
the display will show “DAY-MONTH: NO DATA.”

GSS Compact Sampler
Section 2 Preparing the GSS
The following checklist can be used as a guide to prepare the GSS
for use:
1. Inspect the pump tube, section 2.1
2. Check the discharge tube, section 2.2
3. Install the bottle, section 2.3
4. Connect a power source, section 2.4
5. Connect a suction line and strainer, section 2.5
6. External connections (optional), section 2.6
7. Place the GSS in position, section 2.7
2.1 Inspecting the Pump
Tube
Periodic inspection of the pump tube is advised. If the pump tube
fails, the GSS will not be able to collect samples.
WARNING
Moving parts can cause injuries. Remove power before
inspecting pump tube.
To inspect the pump tube:
1. Disconnect the power from the 12V Input Power connector.
2. Remove the pump housing cover by loosening the four
thumbscrews.
Thumbscrew
Cover
Figure 2-1 Pump housing cover and thumbscrews
2-1
GSS Compact Sampler
Section 2 Preparing the GSS
3. Visually inspect the pump tube for cracks where it is compressed by the rollers. If the tube is cracked, it must be
replaced.
4. Visually inspect the inside of the pump housing. The housing and rollers should be free from debris.
5. Replace the pump housing cover and tighten the thumbscrews.
Note
The GSS will display a pump tube warning as part of the View
Log screens when it exceeds 500,000 pump counts, which is
the recommended pump tube replacement interval. The pump
tube warning is based on a number of pump revolutions. The
GSS cannot “detect” a weak or worn pump tube, but the pump
tube replacement interval should be sufficient for most applications. The GSS automatically resets the pump tube count to
500,000 after it displays the warning message.
2.2 Discharge Tube
The discharge tube is located inside the center section. It is a 3/8
inch (9 mm) I.D., 81/4 inch (210 mm) long piece of medical-grade
Silastic™ tubing.
The discharge tube should be well fitted over the bulkhead fitting
and routed through the tube guide. The tube must be free of
twists or kinks. The tube should extend about 1 1/2 inches (38
mm) past the end of the tube guide (even with the bottom of the
center section). This length of tubing is necessary for the GSS to
detect an overfilled bottle.
Figure 2-2 Discharge tube and tube guide
2-2
GSS Compact Sampler
Section 2 Preparing the GSS
2.3 Installing a Bottle
The base section of the GSS is designed to hold a 1 gallon (3.8
liter) polyethylene bottle (P/N 68-2950-003). This bottle requires
use of the bottle deck. To install the bottle, place the bottle deck
into the GSS base section. Set the bottle on top of the bottle deck.
2.4 Installing a Power
Source
The GSS must be powered by a 12-Volt DC power source.
Teledyne Isco recommends using the Model 946 Lead-Acid
Battery, 6.5Ah.
To install the power source:
1. Place the power source into the center section recess. Refer
to the Figure 2-3 for the correct position:
Figure 2-3 Model 946 lead-acid battery installed
2. Secure the power source by pulling the elastic bands over it
and attach the clip to the two posts. Note that there are
two sets of holes – use the set that places the clip against
the power source.
3. Attach the two-pin connector to the Input Power connector
on the back of the controller.
2.5 The Suction Line and
Strainer
The suction line carries the liquid from the sampling point to the
GSS pump tubing. The GSS is designed to use:
• 1/4-inch (6 mm) I.D. Vinyl tubing
• 3/8-inch (9 mm) I.D. Vinyl tubing
The strainer reduces the possibility of debris plugging the
suction line. Several types are available to choose from.
• Standard Weighted Polypropylene (3/8 -inch I.D. only)
• CPVC body (3/8-inch I.D.)
• Stainless Steel 1/4 and 3/8
2-3
GSS Compact Sampler
Section 2 Preparing the GSS
To prepare the suction line and strainer:
1. Cut the suction line to the shortest feasible length.
2. Attach a strainer to the suction line.
3. Connect the suction line to the pump tube.
2.5.1 Cutting the Suction
Line
The suction line should be cut to the shortest feasible length to
extend battery life. The suction line can be easily cut with a
knife. When cutting the suction line, keep in mind that the
length must be cut to the nearest whole foot. Measure the length
from end to end, without the strainer or tubing coupler.
If you have altered the length, enter the new suction line dimensions using the Program option on the standby screen (Section
3.3).

Section 2 Preparing the GSS
2.6 Connecting External
Devices
The GSS can be used with a rain gauge or liquid level actuator.
These devices connect to the 6-pin Flow Meter Connector located
on the back of the GSS controller.
The sampler inhibit input from these devices can delay the GSS
operation until monitored user-defined conditions are met. For
more details, refer to Section 3.4, Sampler Inhibit.
Note
Rain Pulse input signal (pin C) requirements – a 5 to 15 volt
DC pulse or isolated contact closure of at least 25 milliseconds
in duration.
Note
Sampler inhibit signal (pin F) requirements – a low (grounded)
level of at least 5 seconds inhibits the operation. A high (or
open) level of at least 5 seconds in duration restores the operation.
2.7 Positioning the GSS
There are a few considerations when selecting a site for the GSS.
The foremost concern should be personal safety.
WARNING
The installation and use of this product may subject you to
hazardous working conditions that can cause you serious
or fatal injuries. Take any necessary precautions before
entering the worksite. Install and operate this product in
accordance with all applicable safety and health
regulations, and local ordinances.
The following points should also be considered:
• Level surface – The GSS should be placed on a level
surface to prevent tipping or spills.
• Support – The surface or mounting method must be able
to support the GSS at full capacity.
• Environmental – The GSS is designed for use in harsh
environments. However, you should avoid installing the
GSS in locations where its components are subject to
chemical attack. Also, prolonged exposure to direct
sunlight will eventually damage the ABS exterior.
• Avoid submersion – Although its controller will resist
damage (rated NEMA 4x, 6), the GSS cannot prevent
the liquid from entering the base and center sections.
• Accessibility – The GSS must be installed in a location
where it can be recovered easily without tipping or
difficult maneuvering.
• Security – The location may need to provide some degree
of security to prevent tampering or vandalism.
2-5
GSS Compact Sampler
Section 2 Preparing the GSS
• The GSS can be installed in a manhole using the
optional suspension harness (P/N 60-2954-033). Contact
your sales representative or Teledyne Isco for more
information.
After the GSS is in place, the strainer and suction line should be
properly positioned.
When the strainer is placed in a stream, the intake should be in
the main flow, not in an eddy or at the edge of flow. Its depth in
the stream can also be important. An intake placed at the bottom
of the stream may result in excess heavy solids, while placement
at the top may result in the opposite.
The suction line should always be cut to the shortest possible
length. Route the suction line so it runs continuously downhill,
and avoid loops of coiled suction line or low areas where the
liquid can pool.
The suction line will tend to float when sampling from deep flow
streams. Refer to the chart below. If the depths listed in the chart
are exceeded, anchor the line securely so that the suction line
and strainer do not become dislodged.

2.8 Locking the GSS
Access to the inside of the GSS can be easily secured by placing a
padlock on the carrying handle. Because the carrying handle
must be repositioned before gaining access, locking the handle in
an upright position secures the top cover, center section and controller, and the base section.

HAVE OCCURRED,” or at the end of a sequence of screens, such
as “WARNING: CHANGE PUMP TUBE.”
3-1
GSS Compact Sampler
Section 3 Programming
3.2 GSS Operating States
The GSS has many states of operation. States of operation can be
classified as either “interactive” or “non-interactive.”
Interactive States
• Standby — The display shows “PROGRAM, VIEW
LOG,” and the current time and date. This is an interactive state and the GSS is waiting for your input. You
will see that one of the items is blinking; this is the
current selection and will be accepted if the Enter
button
is pressed. You can change the selected item
by pressing the Arrow button
. Pressing the Go key
from the standby state will start the sampler using
the previously entered program settings.
• Program — The display shows programming options or
number-entry screens. Again, this is an interactive state
through which you can modify the operation of the
sampler controller.
• Paused — Pressing the Stop key
while the sampler
is running a program places the GSS in the Paused
state. This is an interactive state where you can choose
to view the event log, return to the Run state, or halt the
sampling routine.
• Time and Date — The displays shows “ENTER TIME
AND DATE:.” This is an interactive state used to set the
correct time and date.
Non-interactive States
• Off — The display is blank. In this state, a few sampler
functions continue to operate. An internal battery
powers the real-time clock to maintain the correct date
and time. When in the OFF state, the GSS will respond
only to the On/Off button
.
• Run — The display shows information about the
program that it is running. This is typically the current
activity, such as “TAKING SAMPLE,” or the current
status, such as “RAIN: 0.11 OF 0.50 WAITING FOR
RAIN.”
• Done — The display shows “PROGRAM DONE.” This
state reports that the GSS has finished running the
program. Pressing any key except On/Off or Go will
place the sampler in the Standby state.
• View Log — Pressing the Enter button “scrolls”
through the event log.
3.3 Preparation for Use
The GSS is shipped from the factory with the following stored
program settings:
• 0.5 inch rain threshold
• No delay time before sampling
• 3/8" × 25' suction line
3-2
GSS Compact Sampler
Section 3 Programming
To turn the unit on and modify the GSS program settings, press
the On/Off button
. The standby state will be displayed,
showing “PROGRAM, VIEW LOG” and the time and date. (If the
time and date are not current, refer to Section 3.9.)
One of the items will be blinking; this is the current selection and
will be accepted if the Enter button
is pressed. You can
change the selected item by pressing the Arrow button
.
Select Program from the standby screen and press Enter. Fill in
the requested data, pressing Enter after each entry:
1. Enter the rain threshold (the amount of rain recorded in a
rolling 24-hour window that will trigger a sample) by
selecting one of three options: 0.5, 1.0, or 2.0 inches.
If you select 2.0 inches, you will see the following display:
RESET TO 1" AT END
OF MONTH? YES NO
Indicate if you want the trigger amount to reset to 1.0" at
the end of the calendar month.
2. Enter an amount of time (0–45 minutes) to delay before
taking the sample.
3. Select the suction line size by selecting one of two options:
1
/4 inch or 3/8 inch.
4. Enter the suction line length (3 to 99 feet).
After entering the above information, the display will read:
SAMPLER READY...
PRESS GO TO RUN
If you press the Go button, or wait for five minutes, the sampler
will run its program. If there has been any accumulated rainfall
in the last 24 hours, the sampler display will read:
RESET RAIN COUNT?
YES
NO
If you select Yes and press the Enter key, the rainfall accumulation will be zeroed. If you select No and press Enter, or wait five
minutes without pressing any keys, the sampler program will
continue without clearing any rainfall accumulation.
The information displayed next will depend upon the amount of
rainfall that has been received in the last 24 hour period and
what you entered as a rain threshold.
If the amount received has not reached the specified threshold,
the display will read:
RAIN: X.XX OF X.XX
WAITING FOR RAIN
If enough rain has been received, the sample will be taken after
any programmed time delay has passed.
3-3
GSS Compact Sampler
Section 3 Programming
3.4 Sampler Inhibit
Before the GSS takes the sample, it checks the inhibit line of the
Flow Meter connector to see if you have an external device such
as a liquid level actuator connected. If the GSS detects a logic low
(grounded) level, it will suspend the program until the external
device returns the line to a logic high (or open) level.
While the GSS is inhibited it will display the screen below:
RAIN: X.XX OF X.XX
NO RUNOFF DETECTED
When the external device returns the line to a logic high level,
and if detected rainfall has reached the specified threshold, the
sample will be collected following any programmed time delay.
3.5 Sample Collection
Cycle
Each time the GSS collects the sample it runs the pump through
a complete sampling cycle. The cycle consists of three actions –
Pre-purge, Fill, and Post-purge.
Pre-purge – As the GSS waits to collect a sample, some liquid
will tend to enter the suction line and debris may collect around
the strainer. The pre-purge runs the GSS pump in reverse to
force air down through the suction line and strainer. This action
will flush the water from the suction line and clear any debris
near the strainer. The duration of the pre-purge is automatically
calculated by the GSS based on the programmed suction line settings. The Event Mark pin of the Flow Meter connector goes to a
high level (+12 volts DC) for one second at the beginning of the
pre-purge. If you have programmed a delay time before taking
the sample, another Event Mark will occur when that time
starts.
Fill – After a pre-purge, the GSS pump changes its direction to
draw liquid into the suction line. The liquid travels up through
the suction line and pump tube where it then passes through the
liquid detector and peristaltic pump. The liquid is transferred to
the discharge tube via the bulkhead fitting. The discharge tube
deposits the liquid into the bottle. The duration of the fill is controlled by the GSS using input from the programmed volume and
suction line settings, and the liquid detector.
Post-purge – After the fill, the GSS again reverses the pump
direction to force air down through the suction line. This action
clears the entire liquid path. The duration of the post-purge is
automatically calculated by the GSS based on the programmed
suction line settings.
3.6 Run State Displays
The GSS updates its display while it is running a program so you
can monitor the status. The Run State displays are listed below.
Taking the sample –
As the GSS goes through a sample collection cycle it displays the
following:

option is blinking, press the Enter button
.
• Resume In m:ss - When the GSS enters the paused
state, it starts a five-minute idle time-out and will
display the time remaining. Pressing any key other than
On/Off, Stop or Go will reset the timer to five minutes. If
you do not press a button within five minutes, the GSS
will automatically go to the “WAITING FOR RAIN” or
“NO RUN-OFF DETECTED” screen.

3.10 Viewing The Log
The log is a recorded history of the last or currently running
program. The GSS records key program events, such as start and
stop times, and exceptional events, such as power failures.
The log can be viewed by selecting the “VIEW LOG” option from
the standby or paused screens.
As you begin to view the Log, the GSS reports the following:
• Confirms if a sample has been collected.
• If the sample has been missed, the GSS will report the
cause. Possible causes are:
· No liquid detected – The GSS did not detect any
liquid.
3-6
GSS Compact Sampler
Section 3 Programming
· No more liquid – The GSS did detect liquid during
the fill cycle, but it stopped detecting liquid before a
complete sample volume was collected.
· Power fail – Power was lost and sample missed.
· User stopped pump – The user pressed the Stop
button while the GSS was collecting a sample.
· Paused – The GSS was in the paused state when a
sample was to have been initiated.
· Pump jammed – The GSS pump jammed while trying
to take the sample.
• Program start time
• Current status – One of the following will be reported:
· Program completed
· Program halted
· Program paused
• Power lost – If power was lost while the GSS was
running the program, it reports the times it was lost and
restored. This will be reported whether a sample was
missed or not.
• Last programmed date.
• Clock set at (time and date).
• Rainfall amount for the last 14 days plus the current
day.
• Put In Service time and date (if within the last 14 days).

Section 4 Servicing the Sampler
This section contains instructions necessary to perform routine
and preventive maintenance on the GSS and its related components. It also includes diagnostics and repair information. If you
feel you need assistance from a Teledyne Isco service technician,
refer to Section 4.3.1 for contact information.
4.1 Routine Maintenance
4.1.1 Cleaning the GSS and
Components
The GSS controller, top cover, center section, base, and bottle
deck can be cleaned with warm soapy water or by spraying them
with a hose. Avoid using a high-pressure hose to clean the controller. Extreme pressures may damage the label or force water
past the control panel seal.
The connectors should be protected when you are cleaning the
controller. Cap the Flow Meter connector with the attached cap.
Keep a power source connected to protect the 12V Input Power
connector, or use the protective cap that was in place when the
unit was shipped.
The bottle has a wide mouth to make cleaning easier. Wash it
with a brush and soapy water, or use a dishwasher.
The strainer can be cleaned with a brush and soapy water.
4.1.2 Replacing the Pump
Tube
The pump tube is subject to wear during pump operation. It
should be replaced when the GSS displays the pump tube
warning at 500,000 pump counts, or when inspection of the tube
reveals any cracks along its side. The pump counter should be
reset at this time.
WARNING
Moving parts can cause injuries. Remove power before
replacing the pump tube.
To remove the pump tube:
1. Disconnect the power from the 12V Input Power connector.
2. Disconnect the suction line and pull the pump tube from
the bulkhead fitting.
3. Loosen the two thumbscrews and remove the liquid detector cover.
4. Loosen the four thumbscrews and remove the pump housing cover.

5. Pull the pump tube out of the pump housing. Rotating the
pump rollers will help free the tube.
6. Clean the inside of the pump housing if necessary.
Note
Teledyne Isco replacement pump tubes are marked with two
black bands. These bands are used to correctly locate the tubing in the liquid detector and the pump. Position the pump inlet,
or short end, in the upper groove of the liquid detector. The
band should be placed at the outer edge of the liquid detector.
To replace the pump tube:
1. Slip the pump tube under the pump rollers. Rotating the
rollers as you do this will help slide the tube into the pump.
2. Position the pump tube by aligning the bands at the outer
edge of the liquid detector.
3. Replace the liquid detector and pump housing covers. The
thumbscrews should be fully hand-tightened.
4. Connect the pump outlet end to the bulkhead fitting. Connect the suction line to the pump inlet.
5. Reconnect the power.

GSS Compact Sampler
Section 4 Servicing the Sampler
Note
Replacement pump tubes (P/N 60-2954-030) are available
from Teledyne Isco. If you are cutting replacement tubes from
bulk Silastic tubing, cut the length to 27.75 inches (705 mm).
Since the bulk tubing will not have bands to mark the correct
position, ensure that 18.25 inches (490 mm) of tubing is inside
the liquid detector and pump, and that the tube is not kinked
where it fits over the bulkhead fitting.
Note
The peristaltic pump and tube will perform the best when you:
– Use Teledyne Isco replacement pump tubes or bulk tubing.
– Install the tube properly, aligning the inside edges
of the bands with the outside edges of the liquid
detector.
– Follow the natural curve of the pump tube when
fitting the tube inside the pump housing.
– Use the shortest possible length of suction line.
4.1.3 Replacing the
Discharge Tube
The discharge tube does not “wear out” under normal circumstances. However, you may find an occasion when you need to
replace it. To replace the discharge tube:
1. Remove the two thumbscrews that secure the discharge
tube guide.
2. Lift the discharge tube guide and pull the tube off of the
bulkhead fitting.
3. Slide the old tube out of the guide.
4. Insert the replacement tube. Replacement tubes should be
a 3/8 inch (9 mm) I.D., 81/4 inch (210 mm) long piece of Silastic™ tubing, available from Teledyne Isco (P/N
60-2953-032).
5. Push the end of the new discharge tube onto the bulkhead

the Power Products Guide for instructions on servicing Teledyne
Isco batteries.
4.2 Preventive
maintenance
4.2.1 Replacing the Internal
Desiccant
The GSS uses a 4 oz. bag of desiccant (P/N 099-0002-08) to
protect its internal components from moisture damage. When the
internal case humidity exceeds 30%, the desiccant should be
replaced. The internal case humidity is shown on the indicator
visible through the front panel label. The indicator turns pink or
white when the humidity level exceeds the printed value. Ideally,
all three sections of the indicator should be blue.
If the 20 and 30% sections are pink or white, replace the desiccant.
1. Disconnect the power from the 12V Input Power connector.
2. Remove the 10 screws that attach the GSS front panel and
bezel.
3. Remove the bezel.
CAUTION
The GSS controller contains electronic circuitry that can be
damaged by static discharge. Open the controller only in a
static-free environment.
4. Lift the front panel slowly so that the connecting wires are
not pulled excessively.
5. While holding the front panel up, open the cardboard box
and remove the bag of desiccant. Do not try to remove the
cardboard box – it is firmly attached to the side of the case.
Attempting to remove the box may damage it.
4-4
GSS Compact Sampler
Section 4 Servicing the Sampler
Figure 4-3 Internal Desiccant
6. Insert a new or renewed bag of desiccant.
7. Visually inspect the internal components. Corrosion, residue, or other evidence of moisture damage will indicate a
need for cleaning or repair. Contact Teledyne Isco for assistance.
8. Inspect the front panel gasket. It should fit properly in the
case and its surface should be clean and smooth.
9. Replace the front panel making sure the wiring is free of
the gear train.
10. Replace the bezel and screws. Tighten the 10 screws in an
even, cross-torquing pattern.
The internal humidity indicator should return to its normal blue
color in a few hours.
4.2.2 Renewing the
Desiccant
CAUTION
Desiccant may produce irritating fumes when heated. We urge
you to use caution when working with desiccant. Material
Safety Data Sheets are located in Appendix B. To reduce the
hazard of the fumes:
– Use a vented oven in a well-ventilated room.
– Do not remain in the room while recharging is taking place.
– Use the recommended temperature.
To renew the desiccant:
1. Remove the bag from the GSS controller.
2. Place a sheet of brown paper on a flat metal sheet. You can
use a brown grocery bag and a typical cookie sheet.
4-5
GSS Compact Sampler
Section 4 Servicing the Sampler
3. Place the bag on the sheet. If you are recharging several
bags, do not stack the bags on top of each other or allow
them to touch.
4. Place in a vented, circulating forced air, convection oven in
a well-ventilated room. Allow two inches of air space
between the top of the bag and the next rack. Keep the tray
a minimum of 16 inches from the heating element.
5. Heat the bag at a temperature of 240 to 250° F (116 to
121° C) for 12 to 16 hours.
6. At the end of the time period, the bag should be removed
immediately and placed in an airtight container to cool.
7. When the bag has cooled to room temperature, it may be
returned to the GSS controller.
The desiccant will be recharged to approximately 80 to 90% of its
previous capacity. After repeated renewing, the desiccant bag
may require replacement.
Some bags will have the temperature and time for renewing the
desiccant printed on the bag. If that differs from what is outlined
here, use the temperature and time printed on the bag.
4.3 GSS Diagnostics and
Repair
If you are experiencing problems with the GSS, contact Teledyne
Isco's Service Department. Simple difficulties can often be diagnosed over the telephone. Before contacting Teledyne Isco
however, take a few moments to ensure that several common
problems are first eliminated.
• Make sure the power supply is adequate. Low power can
cause a variety of problems. Simply replacing the
battery with a freshly charged unit, or replacing the
power pack can correct many faults.
• Ensure that the liquid delivery system is in good
condition. The tubing should be free from leaks caused
by pinholes or cracks. Make sure the tubing is not
plugged by debris.
• Clear debris away from the end of the strainer and make
sure it is submerged deep enough to supply liquid for
the entire fill portion of the sampling cycle.
If the cause of the problem cannot be determined, the GSS
self-diagnostics routine can be used to test the sampler's functions.
To run the basic level diagnostics:
1. Press
at the Standby display. The GSS
will enter the diagnostics mode.
2. The GSS tests the RAM (Random Access Memory). The
GSS displays the RAM test results for four seconds then
advances to the next test. If the GSS reports “RAM TEST
FAILED” contact Teledyne Isco. RAM stores program settings, log data, internal counters, pump tables, etc.
3. The GSS tests the ROM (Read Only Memory). The GSS
displays the ROM test results for four seconds and then
4-6
GSS Compact Sampler
Section 4 Servicing the Sampler
advances to the next test. If the GSS reports “ROM TEST
FAILED” contact Teledyne Isco. ROM stores the embedded
software.
4. The GSS tests the liquid crystal display (LCD). The cursor
moves across the LCD turning on every pixel, then turning
off every pixel. Next, the GSS displays characters on the
display. Contact Teledyne Isco if the pixels or characters do
not appear correctly.
5. The GSS queries “TEST PUMP?”. Use the Arrow button to
choose an option and press the Enter button to select it.
Select “NO” to skip the pump test and advance to the next
test. Select “YES” and the GSS runs the pump in both
directions – pumping and purging. At the end of each direction, it displays an On/Off ratio. This ratio should be
between 0.50 and 2.00. Contact Teledyne Isco if the ratio is
outside of this range. A count near 1.00 is typical.
6. The GSS queries “TEST LIQUID DETECT?”. Use the
Arrow button to choose an option and press the Enter button to select it. Select “NO” to skip the liquid detect test
and advance to the next function (step 9). Select “YES” and
the GSS enters the liquid detector test (steps 7 and 8).
7. (Liquid Detector Test) The GSS displays “LIQUID
DETECT TEST: PRESS ↵ WHEN READY.” Make sure the
end of the suction line is in water and there is something to
catch the liquid if it is discharged from the pump. Press the
Enter button when you are ready.
8. (Liquid Detector Test, continued) The GSS pumps liquid
and attempts to detect the liquid in the pump tube. It
reports “LIQUID DETECT RINSE (#)” as each of the five
rinse cycles are accomplished. When the GSS does not
detect liquid it reports the reason and waits for a response.
At this point you should:
a. Verify that liquid was present in the pump tube during
the pumping.
b. Verify that the pump tube is installed correctly. The
inside edges of the black bands should be even with the
outside edges of the liquid detector.
c. Make sure the liquid detector cover is firmly seated
over the pump tube and the thumbscrews are tight.
After checking the items above, rerun the liquid detect test
by pressing any button (except the Stop and On/Off) to
return to step 6. If the above steps did not remedy the
problem, contact Teledyne Isco. If you press the Stop button, the GSS skips the liquid detector test and advances to
step 9.
9. The GSS queries “RE-INITIALIZE?”. Re-initializing the
GSS resets the current program settings to the factory
defaults and clears the log. To skip the reset, select “NO”
and the GSS returns to the Standby state. To reset the program settings, select YES. The GSS will ask if you are

sure. Select YES and the GSS will load the default settings
and turn itself off.

4.3.2 Return Instructions
Should it become necessary to return the GSS to the factory for
repair, please contact Teledyne Isco first and obtain a Return
Authorization Number (RAN). This will aid in the prompt repair
and return of the sampler.
When returning the GSS, the unit should be cleaned and packed
in the original shipping containers. If the original container is
not available, prepare the sampler as described below.
1. Assemble all of the components, latching the sections
together.
2. Place the sampler in a bag.
3. Select a cardboard box at least 6 inches (150 mm) longer in
each dimension.
4. Place the sampler in the box.
5. Fill the box equally with resilient packing material (shredded paper, bubble pack, expanded foam pieces, etc.).
6. Include a note describing the malfunction or reason for
return, and reference the RAN.
7. Seal the box and ship to the address listed below.
Consulting with Teledyne Isco’s Service Department will often
determine that only the GSS controller requires servicing. The
controller can be removed and shipped without the top cover,
center section, and base to save freight charges. To remove the
controller and ship it:
1. Disconnect the suction line from the pump tube.
2. Disconnect the pump tube from the bulkhead fitting.
3. Disconnect any items connected to the 12V Input Power
and Flow Meter connectors. Place the cap on the Flow
meter connector port.
4. Release the two latches holding the center section and base
together.
5. Turn the center section over and remove the four screws
that mount the controller.
6. Place the controller in a bag.
